Euodynerus (Euodynerus) fastidiosus (de Saussure, 1853)

( Figs 7I–O ; 14F ; 15Q, X ; 16F, L )

Odynerus fastidiosus de Saussure, 1853: 154 (key), 189, ♀ (in subgenus Leionotus ) — “L’Algérie” (MNHN).

Odynerus germabicus Radoszkowski, 1893: 77 , ♀ (in subgenus Lionotus ) — [ Turkmenistan] “ Germab ” (ZMB [examined]).

Distribution. Trans-Palaearctic taxon, ranging from the Iberian Peninsula in the West to Central Asia and China in the East, reaching the Maghreb, the Arabian Peninsula and Pakistan in the South.

Notes. Available genetic data show that the Italian population of E. fastidiosus differs from those occurring from the Balkan Peninsula to Central Asia by 2.37%, with the latter populations not showing any genetic variability ( Fig. 2 ). A similar trans-Adriatic genetic gap is observed in the genus Stenodynerus ( Selis et al. 2024) and other species of Euodynerus as well.

FIGURE 2. Phylogenetic tree (Neighbor-Joining) of Euodynerus (Euodynerus) based on the mitochondrial COI gene. Ancistrocerus gazella (Panzer) was used as an outgroup. Numbers adjacent to branches represent bootstrap support (values of <75 are omitted); only the species occurring in the considered area are highlighted. Countries are abbreviated using ISO 3166-1 alpha-2 codes. Continues in Fig. 3.
